HOSE-MENDER.

Specification of Letters Patent.

Patented May 6, 1919.

Application filed February 10, 1917. Serial No. 147,937.

To all whom it may concern:

Be it known that I, JACOB MERZ, a citizen of the United States, and residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Hose-Menders, of which the following is a specification.

This invention relates to hose menders of the type employed for mending garden hose and which embody in their organization, a nipple to be inserted into the hose, and clamping means cooperating with said nipple for securing the meeting ends of the hose sections in place thereon.

It is Well known that in using garden hose, the latter will eventually lourst at points which have become weakened as a result of defective construction and of unequal wearing qu'alities. This condition does not necessarily render the Whole length of hose unfit for use, and the same may, therefore,by means of the menders. in question, be readily repaired for further effectual service. In effecting the repair, it is usual to cut the hose at the bursted point, remove the defective portion, and unite the ends of the sections thus formed, by clamping them on the nipple, as mentioned above. Many forms ofmenders for this purpose, have been heretofore devised and have proven more or less successful in operation, the chief objections encountered in these prior structures being an objectionably high cost of production in the manufacture of one which will operate effectively in uniting the hose sections.

This invention has among its objects, therefore, to provide a simplified form of men-der'through the medium of which the hose sections may be properly united and which, at the same time, may be made at a sufficiently low cost of production.

With the above and other objects in view, the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings,

Figure 1 is a view in elevation of a garden hose, showing the component sections thereof united by means of a men-der embodying Fig. 2 is a longitudinal section taken on the line 22, of Fig. 1

Fig. 3 is a perspective view of the nipple;

Fig. 4 is a perspective view of one of the clamping rings or hands;

Fig. 5 is an edge view of the clamping r1ng, showing the locking lever in released posltion and with the ring expanded prepaaatory to being applied over the hose; an

Fig. 6 is a similar view showing the lever locked in position with the ring contracted to hose clamping position;

Referring to the drawings, it will be seen that the mender, which is applied for connecting the meeting ends of the hose sections 1 comprises a nipple2 and a pair of spring clamping rings or bands 3, which are adapted to be applied for retaining the hose sections in place on the nipple, as seen in Figs. 1 and 2.

Thenipple 2 which is of tubular form and is made by drawing or pressing a sheet metal blank into shape, is expanded at suitable points to provide annular ribs, shoulders or enlargements 4: and 5 arranged in pairs and adapted, when the nipple is inserted endwise into the hose sections, as seen in Fig. 2, to expand the hose at points remote from the meeting ends thereof, thereby produoing on each hose section, a pair of distinct relatively spaced annular enlargements 6 and 7, disposed to receive one of the clamping rings 3 between them and 'cooperate therewith for retaining the hose securely in place on the nipple, it being noted that the shoulders 4 on end portions of the nipple, taper to the internal diameter of the hose, thereby adapting the nipple for ready insertion into the hose section.

The clamping rings 3, which are indentical in construction and operation, each consists of a suitable length of spring sheet metal, shaped as shown, to form a split ring adapted to be drawn together and locked in closed condition by means of a locking cam-lever 8, whose. head portion seats in a slot 9 formed in one end of the band, and is pivoted to the latter by a transverse pintle 10 j ournaled in bearing eyes 11, formed by bending the terminal of the band, as shown. The body or tail portion of the lever projects through a bearing slot 12, formed in the other terminal of the band, this slot being closed to provide, at its outer end, a bearing portion 13, which rides over the adjacent face of the lever during manipulation thereof to contract the band and initially seat within a recess 14, formed at the juncture of the tail portion of the lever with its head portion. The end portion of the band, having the slot 12 therein, is bent as shown, to provide a bearing recess 15 formed to fit over the bearing eyes 11, and insure a secure closing engagement of the ends of the band when contracted by means of the lever into clamping engagement with the hose.

Struck from the band at a point for engagement with the end of the lever when turned to locking position, is a retaining finger 16 adapted to be bent downward over the end of the lever and secure the same in locked position. The formation of this finger leaves a recess, as shown in Fig. 4, which is adapted to receive the end of the lever as hereinafter described.

In the operation of mending the bursted hose, the damaged portion or section will be cut out, and the clamping rings or bands 3 applied over the ends of the resultant hose sections and moved backward on said sections, a sutlicient distance to permit of the ends of the hose being properly applied over the nipple. 'After the nipple has been properly inserted, the bands in expanded condition, will then be moved to position for each of them to lie between the adjacent pair of enlargements 6 and 7, produced by the expansion of the hose under the action of the annular shoulders 4t and 5. After the bands have been properly positioned,ras explained, the locking levers are manipulated for contracting the bands to tightly embrate the hose circumferentially and compress the hose, at the point encircled by the band, into the annular depression in the nipple between the shoulders at and 5. compressing the clamping bands is the same in each instance and is accomplished by engaging the free end, of the cam-lever and swinging the same in a counter-clock wise direction, as indicated by the dotted arrow in Fig. 5, the lever being swung completely over, until the end recess 15 is seated snugly over the bearings 11, and until the free end of the lever enters the recess in the band formed by striking up of the lug 16 and rests against the hose section in position to be engaged by the finger 16, which may now be bent down for securing the lever in position in the recesses against axial and radial displacement with the band compressed and hose section securely clamped on the nipple. By tapering the ends of the nipple, the nipple can readily be inserted into the hose sections so as to expand these hose sections over the nipple shoulders. When, therefore, the bands are clamped over the hose between the shoulders, the hose is The operation of simply moved to neutral condition between these shoulders, so that wrinkling will be avoided, and tight joints secured.

It is to be particularly noted that the nipple may be made in one operation and may, therefore, be produced very cheaply, and further, owing to the provision of the shoulders on the nipple, which form spaced enlargements on the hose sections, a simple clamping band, such as described, may be employed for holding the hose section in place on the nipple. v

Furthermore, it will be noted that 'the clamping band described, comprises a minimum of parts which may be struck from sheet metal and readily assembled, and that, therefore, these clamping bands may be made at a very low cost.

From the foregoing, it is apparent. that the device accomplishes the stated objects of the invention, it being understood that in attaining these ends, various minor changes may be made in the details herein set forth, without departing from the spirit or scope of the invention.

Having thus described the what is claimed is:

1. A hose mender, comprising, a nipple having a pair of relatively spaced annular shoulders at each end thereof larger than the bore of the hose sections to be joined,

invention,

the endshoulders tapering to the ends of the nipple to permit the insertion of the "nipple into the ends ofthe hose sections, said shoulders being adapted, when the nipple is inserted into the hose sections, to expand the latter to form a pair of distinct, relatively spaced annular enlargements therein at each end of the nipple, and clamp ing bands applied over the hose sections, one between each pair of said enlargements, and constructed and operable for clamping the hose sections in place on the nipple.

2. A hose mender, comprising, a sheet metal nipple expanded to form a pair of I relatively spaced ribs at each end thereof larger than the bore of the hose sections to be oined, the end ribs tapering to the ends of the nipple to permit the insertion of the nipple into the ends of the hose sections, said ribs being adapted, when the nipple is inserted into the hose sections, to expand the latter to form a pair of distinct, relatively spaced annular enlargements therein at each end of the nipple.

In testimony whereof I atlix my signature this 23rd day of November, 1916.

JACOB MERZ.
